Context (Environment)

Detailed Description

version: github.com/go-redis/redis/v8 v8.11.5 problem scenario: Nearly two million calls per minute are made to interfaces such as "redis/hgetall" and "redis/set"

Possible Implementation

[Duanshouze]

When the number of calls to Redis-related interfaces such as 'redis/hgetall' suddenly increases, the above-mentioned exception occurs, accompanied by a sudden increase in disk block device read bandwidth.
